FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 605,712, dated .Tune14, 18.98.

Application filed July 30, 1897.i Serial No. 646,501. (No model.) l

To au whom it may concern.:

Be it known that I, HENRY HAYNEsVof Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement' in Flushing Apparatus, of which the following is a full,clear, and exact description. v

The object of my invention is to provide a flushing apparatus especiallyadapted for use with Water-closets; and the object of the invention isto provide'an apparatus of such description in which the water will beadmitted to the tank while the seat of the closet is pressed down orduring the period that the closet is in use and whereby Whenthe seat isrelieved from pressure the water will immediately iiow from the tankinto the bowl.

Another object of the invention is to provide a system of valves forcontrolling the supply of water to the tank and the discharge of waterfrom the tank to the bowl,'whicl1 system of valves will be exceedinglysimple, durable, and economic, and, furthermore, to provide a simplemeans for operating the said valves by raising and lowering thecloset-seat.

The invention consists in the novel construction and combination of theseveral parts, as Will be hereinafter fully set forth, and pointed outin the claims.

Referenceis to be had -to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding partsin all the figures.

Figure 1 is a vertical section through a iiushing-tank having theimprovement applied and a side elevation ofthe valve-casing, thedischarge-pipe, and the connections between the said pipe and bowl andthe pull-rod and seat. f Fig. 2 is an 'enlarged-vertical sec.

tion through a portion of the bowl and through that portion of theapparatus which is adjacent to the bowl.- Fig; 3 isV an enlargedtransverse section through the tank, the loat, and air-valve casing forthe tank, and likewise a vertical section through the casing for thesupply and discharge valves of the tank and through the water inlet anddischarge pipes.v

Fig.`4 is an'enlarged'vertical section through a portion of the tank,the discharge and supply valves, and their casings, and Fig. 5 is ahorizontal section through a slghtly-modilied form of thevalvemechanismadapted to be placed ina position removed from the flushing-tank andunder the seat, which is shown 4in plan.

The flushing-tank A may be made of any suitablematerial and isair-tight. An opening is made in the top of the tank, which openingreceives a casing 10. The bottom portion of the casing is of greaterdiameter than the top and is provided with flanges 11, arranged forattachment to the inner face of the top of the tank, and slightly abovethe flanged portion Vof the casing an annular and preferably conca-vedvalve-seat 12 is produced.` Below the casing within the tank aguide-plate 13 is horizontally supported and spaced from the casing 10by bolts l15 and sleeves 14. A iioat 16,v preferably iiat, is providedWith a stem 17, which extends upward through an opening in theguide-plate 13 and the top of the casing 10. A valve 18 is secured onthis stem, adapted to control the supply Y of air to the flushingftank,and this valve usually consists of 'a disk,which is secured on the stem,and as'eniispherical elastic body erably interiorly-threaded flange, asshown in Fig. 4. The plate 19 has' anfopening 2O in its centralportion,and the bottom edge of the said opening is cut away to form aconcaved annular valve-seat 21. (Shown also in Fig. 4.) A` casing 22 isattached to the valved portion of the plate` 19, and the bottom portionof said casing is contracted, forming a neck 23, eX- teriorly threaded,as shown in Fig. 3. A second plate 24 is located above the plate 19,attached to the flushing-tank- This plate 24 is provided with anupwardly-extending iiange 25, which receives vthe lower end of anupwardly-extending casing 26, this lattercasing being entirely Withinthe tank. The pl'ate 24 is separated from the plate ,19 andi isi held inposition by bolts 28' and sleev`es'27. (Best shown in Fig. 4.)

An opening 29 is made in the central portion of the upper plate 24, andthe upper edge IOO 'second section Jr() of the valve-stem is IAO of thesaid opening is cut away to form an anl nular concaved valve-seat 30. Aspider-guide 3l is secured at the neck portion of the lower casing Blanda similar guide 32 is placed within the upper casing 2b' near its top. Avalve-stem 33 extends within the lower casing and practically throughthe upper casing, passing likewise through the openings in the twoplates l0 and 2l. This valve-stem carries a lower discharge-valve 3l andan upper supply-valve S5, one being adapted to open when the othercloses. The lower or discharge valve 3l is larger than the upper orsupply valve 35, but both valves are practically ot' the sameconstruction, each comprising a metal disk a, which may be connectedwith the valve-stem, and a semispherical elastic body a. The lowerdischarge-valve 3l seats when carried upward, and the upper or supplyvalve 35 seats when it is carried downward. A sleeve 315 is slipped overthe valve-stem 33, being placed between the two valves, and at each endof the sleeve a ilange 37 is made, one of: the [ianges engaging with thedischargevalve and the other flange with the supplyvalve, as shown inFig. l.

A pull-rod 3S is screwed upon the lower end of the valve-rod 33 to anengagement with the lower or discharge valve, holding the latter inplace, and a union 39 is screwed upon the upper end of the valve-stem33, serving to hold the upper or supply valve in place. A

screwed into the union 39 and passes through the upper guide 232, thepull-rod 3S passing through the lower guide 3l, as shown in Fig. 3. Thislower guide 3l insures the valves sliding through to their seats.

The water-supply pipe 50 is passed usually through a side of the tankand is secured in the upper end of the valve-casing 26, as illustratedin Fig. 3. A discharge-pipe 5l is secured to the lower end of the lowervalvecasing 22. This discharge-pipe is of anydesired diameter andextends downward, usually through a support 52, attached to a wall oradjacent tothe closet-bowl 53. The lower end of the discharge-pipe 5l issuitably shaped to enter the bowl. At the bend of the discharge-pipe 5la stufling-box 5l is formed, through which stulling-box the pullrod 3Spasses. The lower end of the pull-rod is provided with a head 55, and aspring 5G is coiled around the pull-rod, having bearing against the saidhead and against the stuffing-box. This spring serves to keep the upperor supply valve from leaking during low pressure in the water-main, andthe spring likewise serves to assist in holding up the front of thecloset-'seat when the latter is not in use.

The seat 57 is connected with the support 52 or with an equivalentsupport by means of a hinge 5S of suitable construction, and the seat isso mounted upon the support that it will have normally at least an inchplay to and from the bowl. The pivot 5S) of the hinge is above the levelof the seat, and the upper end of a lever 60 is loosely mounted on thepivot-pin of the hinge, extending downward through an opening inthehinge and an opening 6l, provided between the rear of the scat 57 andthe support 52, as shown in Fig. 2. The upper end of the lever GO ispreferably at an angle to its body, and the straight-forward edge of thelever just beneath the anguiar top is adapted for engagement with theback ot the seat 57, and in order that the lever shall not mar the seata protecting-plate 2 is attached to the seat opposite the lever, as isalso shown in Fig. 2. The lower end of the lever 60 is provided with alongitudinal slot G3, in which a pin (il is adjustably secured, and saidpin is connected with a link G5, the link beingpivotallyattached to anarm 0f a bell-crank lever fill, the opposite arm of the lever beingpivotally attached to the head of the pull-rod.

In operation when the seat 57 is unoccupied it will be raised at itsouter end, as the spring 5G, pressing downward on the horizontal memberof the elbow-lever GG, will cause the said elbow-lever to force thelever Gl) forward and thereby carry the seat to an upward inclination atits forward edge, and the spring 56 will likewise serve at that time tokeep the su pply-valve 35 closed and the discharge-valve f3'- open, sothat all the water that may have been contained in the tank will haveilowcd out through the discharge-pipe 51 into the bowl. The adjustablepin 6l, connecting the link G5 with the lever (50, is made adjustable inorder that the throw of the valves may be controlled from said lever.lVhen the seat is pressed downward onto the bowl, the seat as thusforced downward will force the lever GO rearward and cause theelbow-lever GG to force the pull-rod 38 upward against the tension ofthe spring 5G, thereby causing the dischargevalve 3i to close and theinlet-valve to open, as shown in Fig. 4C. The result will be that whilethe lid is held down the water will flow into the tank until it hasreached such a level as to cause the iioat to close the air-valve 18,and in a short time the air-pressure in the tank will become equal tothe water-pressure in the supply-pipe and the supply of water willcease. As soon as the lid is released from pressure the spring 5G actson the lever G0 to throw the seat up and unseat the dischargevalve 34,closing the supply-valve 35, and, as stated in the first place, all thewater in the tank will flow downward to the bowl.

In the construction shown in Fig. 5 the arrangement of the valves isespecially adapted to admit of the valves being placed at a point belowthe seat and at the rear of the bowl. This construction embraces a valvecasing 68, into which the discharge -pipe G7 enters near one end and isconnected with the bowl. Vithin the casing, just in front of theentrance of the discharge-pipe G7, a vertical partition 60 is formed,havingan opening therein, at which opening a discharge-valve is adaptedto be seated. Parallel with the par- ICO TIO

tition 69 a .second vertical partit/ion 7l is `formed in the casing,having an opening at which the inlet-valve 72 is to be seated, the inletor supply valve being at the outside of lthe partition 7l, while thedischarge-valve 70 is at the outside of the partition 69.

, partitions 69 and 7l, and the water-supply pipe 76 is connected withthe casing atY that end near which the inlet-valve 72 is placed. The twovalves are secured upon the saine stem l73, and this stein is coupledtoa pullrod 74, passed through a bushing 75 at the end of the casing,the pull-rod terminating in a head 55 the same as the pull-rod in theother views heretofore described. The outer portion of the pull-rod issurrounded by a spring 56, acting in the same inanner as the springdesignated by the same reference-numeral in the other views. The headportion of the pull-rod is connected with a bell-crank lever 77, and thesaid bell-crank lever is connected by a link-'7S with a seat-lever 60.

Having thus described my invention, I

l claim as new and desire `to secure by Letters cap having a valveseatforined therein, connected valves, one valve being arranged to close theoutlet for the water-supply pipe and the other valve being arranged toclose the inlet of the discharge-pipe, one valve seating when the otheris unseated, and a pull-rod connected with the valve, whereby the valvesare operated, for the purpose specified.

2. In a lushing apparatus, the combination, with a tank, a water-supplypipe leading into the tank, the said tank being provided with -anopening in its bottom and a plate having a valve-seat supported withinthe tank above the opening, forming a cap for the outlet end of thesupply-pipe, of a discharge-pipe iitted in the opening in the tank andprovided at its top with an apertured cap having a valve-seat formedtherein, con-Y nected valves, one valve being arranged to close theoutlet for the water-supply pipe and the other valve being arranged toclose ,the inlet of the discharge-pipe, one valve seating when the otheris unseated, a pull-rod connected with the valve whereby the valves areoperated, a tension device normally holding the pull-rod in a downwarddirection, causing the supply-valve to be normally seated, a lever, anda connection between the said lever and pull-rod, whereby the said rodmay be forced upward against the resistance of the said tension device,as and for the purpose specified.
